I think this is incorrect but I could be wrong.
You can not buy a Pixel device preloaded with GrapheneOS. They only come from Google with their standard Android and it’s up to the end user to install GrapheneOS. Unless you buy a used Pixel device with GrapheneOS already installed.
Yeah I’d consider that as a used phone. I’d only get the hardware from the OEM and install GrapheneOS myself. Less chance of man in the middle. It’s super easy to install using the web installer.
